Abstract: A correction method for a dental cutting machine includes inputting a machining program of a correction piece to the dental cutting machine, mounting a material for the correction piece to the dental cutting machine to which the machining program has been input, machining the correction piece from the material using the dental cutting machine executing the machining program, measuring a dimension of a predetermined portion of the correction piece machined in the machining, calculating a correction value based on the dimension measured in the measuring, and inputting to the dental cutting machine the correction value calculated in the calculating.

Abstract: A holding attachment includes a holding portion with a round or substantially round columnar hole shape in which a held portion of a material before cutting is inserted and a mounting portion that is mounted on a work mount of a cutting machine. The mounting portion includes at least one pin that is inserted to at least one pin insertion hole provided in the work mount and at least one engagement portion that is engaged with at least one rotation stopper provided in the work mount. A position reference portion of the material before cutting is recessed from a round or substantially round columnar outer peripheral surface of the held portion. The holding portion includes a fitting portion fit to the position reference portion of the material before cutting.

Abstract: A method of post-curing a modeled object in a green state based on modeling data generated according to a working model includes a curing step of exposing the modeled object to light while the modeled object is fitted to the working model to secondary-cure the modeled object.
